DETAILED DESCRIPTION

Referring now to FIGS. 1-18, a firearm support system (FSS) 3100 is disclosed as comprising a buffer tube mount (BTM) 3102 and a receiver 3104. The BTM 3102 comprises a first complementary component 3106 and the receiver 3104 comprises a second complementary component 3108 that is configured for selective engagement with the first complementary component 3106. In this embodiment, the first complementary component 3106 comprises a raised button, knuckle, and/or male component generally comprising a rounded head 3210 carried by a central shaft or neck 3208. In this embodiment, the second complementary component 3108 comprises a U-shaped receiver channel configured to allow the central shaft to slide into the U-shaped receiver channel while also being configured to at least partially selectively capture the first complementary component 3106.

The BTM 3102 can be coaxially received on a buffer tube 3103 or other cylindrical firearm component and secured to in place with a castle nut 3105 or other retention device. Most generally, the BTM 3102 can be installed and uninstalled from an AR-15 type firearm in substantially the same manner as commercially available receiver end plate and in a manner commonly known by those skilled in the art of assembly and/or disassembly of AR-15 type firearms. In some cases, the FSS 3100 can be used in conjunction with use of a should strap and/or shoulder carrying sling by connecting a quick disconnect to the quick disconnect feature 3107 of the BTM 3102. The receiver 3104 may comprise plastic and/or any other suitable material, including, but not limited to, metal. A curvature 3110 in the receiver 3104 allows for a comfortable fit with openings 3112 on each end of the receiver 3104 for the belt to be run through and attached to a user on the hip and/or waist area. Alternative embodiments of the receiver 3104 can comprise different features for attachment to segmented straps (MOLLE straps). The second complementary component 3108 may comprise a long vertical area that allows the male part of first complementary component 3106 to slide into a channel of the second complementary component 3108 and be selectively held in place. In this embodiment, the receiver 3104 comprises a locking mechanism 3114 to keep the joinder between the first complementary component 3106 and the second complementary component 3108. The locking mechanism 3114 comprise a deflectable biased integral ramp 3116 that carries a catch 3118 that allows selective keeping of the joinder between the first complementary component 3106 and the second complementary component 3108. The receiver 3104 can be formed via a plastic injection mold. With sufficient introduction of the knuckle portion of the first complementary component 3106 into the channel of the second complementary component 3108, the BTM 3102 can be automatically captured by the receiver 3104. The BTM 3102 and the receiver 3104 can then be safely separated by simply pressing and deflecting the integral ramp 3116 toward the curvature 3110 until the catch 3118 no longer obstructs removal of the first complementary component 3106. With the integral ramp 3116 sufficiently deflected toward the curvature 3110, the first complementary component 3106 can be removed from the second complementary component 3108. FIG. 3 shows the first complementary component 3106 captured by the second complementary component 3108. FIG. 4 shows the first complementary component 3106 near engagement with the second complementary component 3108 but with the first complementary component 3106 not captured by the second complementary component 3108. FIGS. 3 and 4 also show the BTM 3102 in different orientations relative to the receiver 3104. In some embodiments, the BTM 3102 can rotate relative to the receiver 3104 even when the first complementary component 3106 is captured by the second complementary component 3108.

Referring more specifically to FIGS. 6-11, the BTM 3102 generally comprises a ring 3200 sized and configured to receive a buffer tube 3103 or other cylindrical component therethrough. The BTM 3102 may comprise a key 3202 for ensuring a selected angular orientation relative to the buffer tube 3103 or other cylindrical component that may comprise a complementary channel for receiving the key 3202. The BTM 3102 may further comprise a shelf 3204 that, when installed on an AR-15 type firearm, extends from the ring 3200 toward a rear of the firearm and/or toward the castle nut 3105. In some embodiments, the first complementary component 3106 comprises an axis 3206 extending from the shelf 3204 along which a neck 3208 and a head 3210 are substantially coaxially aligned. In some embodiments, the axis 3206 is laterally offset from the ring 3200. In some embodiments, the head 3210 outer diameter is greater than a lateral length of the ring 3200 (see FIGS. 10 and 11). In some embodiments, the head 3210 outer diameter is greater than a lateral length of the combined lateral length of the ring 3200 and the shelf 3204 (see FIGS. 10 and 11). In some embodiments, the shelf 3204 may comprise a ramp 3212 which allows additional clearance for quick disconnect devices that may be connected to the quick disconnect feature 3107.

It will be appreciated that while the BTM 3102 is shown in a right-handed configuration, alternative embodiments may comprise substantially the same features but in a mirror image so that a left-handed configuration can be obtained. Alternatively, one or more features of the BTM 3102 may be duplicated so that a single BTM provides both right-handed and left-handed compatibility. For example, an additional first complementary component 3106 may be provided to the BTM. In operation, the FSS allows for comfortable and rotatable carriage of a firearm or other device to which a BTM 3102 can be mounted, with the weight of the firearm being transferred to, a support structure to which the receiver 3104 is attached, such as, but not limited to, a belt, vest, wall, post, and/or any other suitable structure for supporting the FSS and an associated firearm and/or device.

At least one embodiment is disclosed and variations, combinations, and/or modifications of the embodiment(s) and/or features of the embodiment(s) made by a person having ordinary skill in the art are within the scope of the disclosure. Alternative embodiments that result from combining, integrating, and/or omitting features of the embodiment(s) are also within the scope of the disclosure. Where numerical ranges or limitations are expressly stated, such express ranges or limitations should be understood to include iterative ranges or limitations of like magnitude falling within the expressly stated ranges or limitations (e.g., from about 1 to about 10 includes, 2, 3, 4, etc.; greater than 0.10 includes 0.11, 0.12, 0.13, etc.). For example, whenever a numerical range with a lower limit, R_(l), and an upper limit, R_(u), is disclosed, any number falling within the range is specifically disclosed. In particular, the following numbers within the range are specifically disclosed: R=R_(l)+k*(R_(u)−R_(l)), wherein k is a variable ranging from 1 percent to 100 percent with a 1 percent increment, i.e., k is 1 percent, 2 percent, 3 percent, 4 percent, 5 percent, . . . 50 percent, 51 percent, 52 percent, . . . , 95 percent, 96 percent, 97 percent, 98 percent, 99 percent, or 100 percent. Moreover, any numerical range defined by two R numbers as defined in the above is also specifically disclosed. Use of the term “optionally” with respect to any element of a claim means that the element is required, or alternatively, the element is not required, both alternatives being within the scope of the claim. Use of broader terms such as comprises, includes, and having should be understood to provide support for narrower terms such as consisting of, consisting essentially of, and comprised substantially of Accordingly, the scope of protection is not limited by the description set out above but is defined by the claims that follow, that scope including all equivalents of the subject matter of the claims. Each and every claim is incorporated as further disclosure into the specification and the claims are embodiment(s) of the present invention.
